hw/nvram: at24 return 0xff if 1 byte address
The at24 eeproms are 2 byte devices that return 0xff when they are read
from with a partial (1-byte) address written. This distinction was
found comparing model behavior to real hardware testing.
Tested: `i2ctransfer -f -y 45 w1@85 0 r1` returns 0xff instead of next
byte
